MMIO write of 00000000 fault at 103ff4?

I ran my Proxmox host this morning and got this at the boot:



Proxmos and its VMs run regularly anyway, but I'd like to understand what is the issue about.
Thanks

hi,

does this happen regularly? or has it started happening recently?

did you upgrade anything recently? what is your pveversion -v output?

sometimes it helps to add nomodeset in the kernel cmdline [0], or blacklisting the nouveau module (in cases where it's incompatible with the hardware).
you can try echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf and reboot your machine to see if it helps.
